Explanation: How far can you see? Everything you can see, and everything you could possibly see, right now, assuming your eyes could detect all types of radiations around you — is the observable universe. In light, the farthest we can see comes from the cosmic microwave background, a time 13.8 billion years ago when the universe was opaque like thick fog. Some neutrinos and gravitational waves that surround us come from even farther out, but humanity does not yet have the technology to detect them. The featured image illustrates the observable universe on an increasingly compact scale, with the Earth and Sun at the center surrounded by our Solar Systemnearby starsnearby galaxiesdistant galaxiesfilaments of early matter, and the cosmic microwave background. Cosmologists typically assume that our observable universe is just the nearby part of a greater entity known as “the universe” where the same physics applies. However, there are several lines of popular but speculative reasoning that assert that even our universe is part of a greater multiverse where either different physical constants occur, different physical laws apply, higher dimensions operate, or slightly different-by-chance versions of our standard universe exist.

I was speaking with someone today who suggested I may want to re-open the recent post that had a coffee discussion. So I am reopening the original post – anyone can request a re-opening to continue their dialogue – the instructions to do so are on the right hand side panel. You can just call or text me too if easier. Michelle mentioned what vessel you might use?

Please keep in mind, with two posts up, there are two places to comment so make sure you are where you want to be.

Thank you for reading today's post. Have an InterStellar Day! ~PrP

    This dialogue seems to be steeped in a brew of antagonism. Of course A simple solution would be for the logic to have an alternative to a brewer or a carafe. What would that be? I’m sure as logical as you are, you can reach into your cup of science and arrive at a taste that would be pleasing to both.

    My answer would be to use a thermos. That way the coffee would stay warm without being re-warmed until you wanted to drink it upstairs.

    My answer would be to suggest that the coffee drinkers use a thermos. It will allow them to keep their coffee warm without the loss of taste due to reheating. So Aliens bring your favorite flavor of coffee up in a thermos. And Michelle, I’d certainly like to brew up something steeping for you, if I am ever in your neck of the woods.

    I have no idea where my post went. This thing is just too complicated.

    Did You Know?

    In cultures around the world, nodding your head up and down to indicate “yes” and shaking your head side to side to indicate “no” is nearly universal, except in some Southeastern European areas such as Bulgaria and southern Albania where they indicate the opposite.

    Just curious why you all are posting about coffee here and not in the other post below this one??? I opened the other post for you so you could continue the convo there. SMH

    Did You Know?

    In the 2016 film Doctor Strange, the characters of both Doctor Strange and the villain Dormammu (via CGI) are played by Benedict Cumberbatch.

    Excuse me for forgetting how this may be displayed for you and how you get into/access the avenue may affect what you are presented with. So if you only see one post you can go to the top of where the comments begin and select the text (name of post) with the left arrow (back arrow) to load the prior post. In this case it’s text = <—7/4/22
    7/4/22 was the name of the post reopened
    Maybe that will help your navigation.

      I think I’ll update the name of the post w [RO] so it is clearer

      We thank you for your efforts. You may go back to your previous methods of operation. We have educated the participants on how to work in that arena.

    Apple to launch ‘lockdown mode’ to protect against Pegasus-style hacks
    Firm says function is intended for users who face ‘grave, targeted threats to their digital security’

    ‘Lockdown mode’ will be part of iOS 16, iPadOS 16 and macOS Ventura released in the autumn.
    Apple is launching a “lockdown mode” for its devices to protect people – including journalists and human rights activists – targeted by hacking attacks like those launched by government clients of NSO Group using its Pegasus spyware.

    Apple will roll out the setting in the autumn and believes it would have prevented previously known spyware attacks by closing down technical avenues for digital espionage. It said the lockdown mode was intended for users who face “grave, targeted threats to their digital security”.

    The news is a sign of how the proliferation of mercenary spyware, or tools that can be used by government clients to hack into any phones and remotely control them, has become a major business concern for Apple and other phone makers.

    While for years Apple appeared to play down the threat to its clients posed by Pegasus and other spyware, including by emphasising that such hack attacks affected relatively few users, supporters of the company’s latest move say the new function acknowledges the seriousness of the threat.

    The protections offered by lockdown mode include blocking most message attachments, blocking incoming FaceTime calls if the user has not previously called the initiator or sent a request for a call, and blocking access to an iPhone when it is connected to a computer or accessory when locked.

    Ron Deibert, the founder and head of the Citizen Lab at the University of Toronto’s Munk School, said the new setting would “definitely” make it more challenging for clients of NSO Group and other companies to successfully target individuals, and compared it to the introduction of two-factor authentication.

    “In other words, it’s introducing some security measure that reduces functionality and user experience in exchange for security. And … we hope other platforms would do something similar,” Deibert said. “We’ve seen the big tech platforms start to address the threats raised by the mercenary spyware industry. We definitely applaud and welcome that.”

    He added that if the new setting was adopted by users, it would “completely reduce the possibility of getting inside and exploiting some flaw in applications or other bits of software” that make it possible for spyware such as Pegasus to infect a phone.

    When an iPhone or other handset is infected with Pegasus, the user of the spyware can in effect take over that phone, accessing messages, pictures and location. The software can even turn a phone into a remote listening device.

    Apple does not disclose the number of its users subjected to Pegasus-style hacks, but its devices have been victim of highly targeted attacks in 150 countries. Pegasus is a hacking program developed and licensed to governments around the world by NSO Group, an Israeli company. It can infect phones running iOS or Android and can be delivered via “zero-click” attacks, which do not require any interaction with the phone’s owner to gain entry to the device.

    Apple, which is suing NSO in the US, said the new mode was designed for users at risk of being targeted by some of the “most sophisticated digital threats, such as those from NSO Group and other private companies developing state-sponsored mercenary spyware.” It described the mode – which will come with iOS 16, iPadOS 16 and macOS Ventura in the autumn – as an optional measure for a “very small number of users”.

    Apple is offering a reward of $2m (£1.7m) to anyone who can find a way round the new setting. It also announced it is making a $10m grant to the Dignity and Justice Fund, a funding initiative established by the Ford Foundation to help it expose and investigate targeted cyber-attacks.

    NSO has said it investigates all credible allegations of abuse against its government clients and that its spyware is only meant to be used to target serious criminals such as paedophiles and terrorists.
    ======================
    Actually NSO is a lying sack of shit. Israel invented the software to target threats to them by moslems, but greed made them sell the software to anyone with the money to pay for the system. They unleashed upon the world a method for stalkers, rapists, governments, pedophiles, anyone who is interested in your privacy to turn your phone into a device that collects data about you. They can use your phone in any way they choose anytime they choose. It becomes their recording device for any sound around you or anything your phone’s camera can see.

    All this Israel did for money. Is there any wonder Israel is universally hated. When you are willing to sell out your own safety for a few dollars more, why is the US so bent on spending billions of dollars to protect them from themselves?
